If you have BCM card remove the kexts Airportitlwm, IntelBluetoothFirmware and BlueToolFixup. Ventura tested and not working well with Intel 9560NGW, if you have Intel 8260/8265 it will work flawlessly. Enjoy!
My specs are:
Whiskey Lake i7-8665U CPU
Intel UHD 620 graphics
14" FHD IPS touchscreen
16GB DDR4
